Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

MFC r314556-r314558

r314556: Correct MDSRCS use in /string/Makefile.inc. - Remove .c files which duplicate entries in MISRCS. - Use the same, less merge conflict prone style in all cases. - Use MDSRCS for mips (.c and .S files both ended up in SRCS). - Remove pointless sparc64 Makefile.inc. - Remove uninformative foreign VCS ID entries.

MDSRCS it intended to allow assembly versions of funtions with C implementations listed in MISRCS. The selection of the correct machdep_ldis?.c for a given architecture does not follow this pattern and the file should be added to SRCS directly.

We've been lax about matching END() macros in asm code for some time. This

is used to set the ELF size attribute for functions. It isn't normally critical but some things can make use of it (gdb for stack traces). Valgrind needs it so I'm adding it in. The problem is present on all branches and on both i386 and amd64.

Optimize the instruction alignment.
